SECTION 1

SIGNALS/CONNECTIONS

SIGNAL GROUPINGS

The input and output signals of the DSP56307 are organized into functional groups as shown in

Table 1-1. Figure 1-1 diagrams the DSP56307 signals by functional group. The remainder of this

chapter describes the signal pins in each functional group.

Note:

1. Port A signals define the external memory interface port, including the external

address bus, data bus, and control signals.

2. Port B signals are the HI08 port signals multiplexed with the GPIO signals.

3. Port C and D signals are the two ESSI port signals multiplexed with the GPIO

signals.

4. Port E signals are the SCI port signals multiplexed with the GPIO signals.
